To all whom it may concerre: I

Be it known tl st. l, LEVI P. hloniinsnrin. a,

citizen of the United States, residin at qlfscle son; in the county of Jackson an Stete of 5 Michigan, have invented certain new and nseiu ing Building-Blocks, of which the following is e; specification, reference being had therein to thgaccompenying drawings.

The invention relates to machines for molding blocks of that t e known as face down" and in which the ottomplate of the mold durin the moldin operation forrns the front lace of the bloc as placed in the-'w all.

The invention consists in certain novelfestures of construction as hereinafter set forth. In the drawin s, Figure 1 isa perspective view of the mac he with the parts in position for the removal of the molded block. Fig. 2 is a cross-section through the machine with the parts in position for melding. Fig. 3 is a detail section on line a: a: of Fig. 2. Fig. 4 is a. section taken in e plane transverse to that of Fig. 2, illustrating the bin ed end plates of themold. Fig. 51s a rear elevation of Fig. 4 with the hinged end plate in open position. I

In the melding of building-blocks-itiscustomery. to vary the width of the block according to the thickness of the wall desired, but the other dimensions- 5. e.,' the and the hei ht-are generally maintained the same for afi full blocks; It is also custom ery in the molding of blocks to support then; 35 both during the molding operation and sub sequently while the cement is setting 'KPGII bottom plates or pallets. These pallets must form a. complete face for the mold, and conseqiliently the pallet must v in width for eac adjustment in the width o the mold. Therefore it is necessary to provide each ma.- chine with a large number of pellets of different widths corresponding to the different widths of blocks to be molded.

It is one of the objects of the -,present invention to reduce the number of pellets necessary for the machine. is r i It is a fnrtherobjeot of rovide means .for quibklydadimtin b 0 ,an

fur- Bis a frame mounted upon the frame A to slide lsterelly in relation thereto, preferably comprisin the horizontal bars 6t, slidsble in hearings in the end frame c of the main frame or with uprights d' at their 7 tendin between these u rights is a cross-bar is vertically e justable, preferebl providing slots d in the uprights, 'throug w ich the clamping-bolted for t e bar e pass. 7 C represents cores which are adjnstably seouter ends, and excured to the cross-bar e and extend laterally therefrom. over the bed or main frame A These'cores are secured to the cross-bar e by elem in --bolts 2 and may be adjusted longitn ina 1y of the bar by suitable means, such as slotting thesber or providing it series of apertures thereih with which the bolts 15 engage. Thus by adiusting the clamping b0 ts e end d the cores 0 may be shifted in position, either longitudinally of the blocker vertically with respect to the bed, the latter adjustment being for forming blocks of ditferent widths.

Parallel to the cross-bar e at one side of the main frame A is a plate D, which iormsone face of the mold and is a ertured at f'fon cores As this plate most vary in height in the arrangement f for each adjustment or longitudinally, it is connected to an upoi the cores vertica preferably detachablgv sight supporting-frame This supportingirame, as illustrated in Fig. 5, comprises the s'ertieel side bars and top and bottom bars The si e bars 9 are vertically slotted at gfor the passage of clamping-bolts i, which, with clamping-plates g fasten t e frame E to the frame A. The piste D is secured to the frame E by any suitable means, such asthe securing-screws h, and when in position its lower ed e will rest directly upon the top bar '5 of, the ilrame A. Thus where a diii'erent width of plsteD is to be used it may be quickly secured to the frame E and the latter edpisted vertically until the bottom edge of the plate 9 rests onthe bed, as inst described.

bed A. The bars a are provided In addition to Slip porting the plate 1) es 7 correspondingly to each variation in width of.

of supporting the the plate D, I referably formthe. plates F of maximum widih and secure thereto detachable lining-plates G of variable width. The plates F are arranged to swing against the ends of the main frame A, while the linin plate G projects inward over the top of said main frame. By this arran ement I avoid the necessity of changing t e plates F for different sizes of block, it being only necessary to replace the lining-plates G by others of suita le dimension.

To complete the mold, another plate ara'l-.

lel to the plate D and a plate arrange horizontall are necessary. The two plates. are prefera l secured to a common sup orting member I I, which is pivotally secured to the main frame A, so as to be capable of a partial rotation. As illustrated in Fig. 2, this pivoted supporting-frame H comprises the end brackets j, which extend horizontally in the osition shown in. Fig. 2, and the skeleton ame k, which extends vertically in the .same figure, perpendicular to the brackets j. :To the brackets j is detachably secured a late I, which forms the bottom of the molil in molding position, but the side face of the block as it is arran ed in the wall. As shown, the. plate I is fashioned to reduce. a rock-face appearance; but it may e of any suitable design or plain,. as desired. The vertically-extending frame It forms the suport for a plate J which constitutes the palet-upon which the moldedblock is removed .from the machine.

i one of considerablygreater width.

' upright position in As has been stated, it is an object of the in-/ -Vention to reduce the number of different sizes of allets for use in molding different sizes of b ooks. This is accomplished by roviding the brackets 7' with slots in w oh the pallets. J may be inserted amf by arrangingsaidgpallets. so as to overlap the edge of the moldeplate I. Thus itris not necessaryto change the width of the-plate: J for each ad- ;ustment in the widthof theblock, and-it is immaterialas to whether. anarrow block is molded with a. pallet of the. same widthor 1 Where narrower plates J 8.I6.I1S0d',15 h888 ma .be sup ported by detachable: blocks-J, w ch are ifurcated to embrace 43116 bracket. 7' and are secured thereto by .set screws 7'.

The frame. Has pivoted. to theframe A,

preferably by stub -shafts H, extending ii therefrom and en agin with bearings H on the main frame T esepivots permit of partiallv rotating the frame H, the ur ose of whichis to change the blockfrom t e acedown position in which it is molded to the which it is supported on the pallet JT This partial rotation of: the frame may be accomplished by the operator bathe use of a suitable lever, such as H w 'oh is sliclingly secured .in bearings H on theframe- H and ma. .posltmn for use.

be drawn outward into or supporting the frame frame H, and the '.withdrawn from the m0 i1 e ts,

-H when rocked as described a leg K is pivotally secured to the outer end of the frame In and will swing during the turning of the frame H into the position shown in Fig. 1. Thus the molded block ma r be turned into upright position very quickly and with very little effort on the part of the operator.

The pallets J are'preferably arran ed on the frame k between end guides 7c, an when the frame is turned down in the position shown in Fig. 1 said pallets may be slid outward between said guides and removed from the machine. To facilitate this sliding movement, .the frame K is preferably out awa at k to form openings, through which the ands of the operator may be insertedjn gras ing the pallet J.

'Tiie various plates which constitute \the mold are locked 1n rigidrelation to each other during the molding operation byprowiding latches L on'the swinging end plates F,.which engage with keepers M on .the frame -H. Theselatches when in engagement with the keepers will rigidly secure the plates F vto the plates G, overlapping the plate I and extending between the lates D and J, will-impart great rigidity to 't e structure.

I It has been stated that thecores G. aresecured to the slidableframe B and are moved by the latter into or out of :the core-openings fin the plate D. Formovin theframe B, I preferably provide a rock-s ft .N, having rock-arms at-its opposite endsand connected by links P with the frame B. One, or

both of the rock-arms O is provided withra socket 0-. at;its upper. end intdwhioh an extension-lever Q may be inserted, by meansof which the shaft ma berocked. and. m0vement imparted to t e framer B. Thus;the

cores may be..quickl rojeeted..-irrto,.and

The parts being thus constructed, their operation is. as follows: i The mold is adjusted to. a size correspondingto the block required selecting. a plate D of a width" corresponding to the width of thewall and.having suitable core-apertures for the size of-cores required. This plate is then secured .by; the screws h to the frame E, and the lattenis .verticall ad'usted .to. bring :thelower edge .of against the top ofthe bed. The clefripfiigsscrews .g are then tightened .to hold the frame E in rigid position. This; adjustment of the frame Ewill pro nly adjust the swinging end frames F, to w ich famngplates G of suitable dimensionsimay nextibe secured. The cores 0 are adjustedinto .registration with the core-openingsfin the plate D by vertically adjusting thecross-bare and clamping it in adjusted position by ithebqlts d", and where-necessary the coresma :fllSQxbG adjusted longitudinally of .the-cross-bar e by shiftin the I clampin -screws e. @A .faceplate having the g esired pattern,v ism-e ,combination'with a bed, of a pluralityof mold sides on o posits sides ofsaid bedand' overthen ceases cured to the brackets 7', and the pallet J is placed in position between the guides 70. his pallet 18 adjusted to have its upper'ed% flush with the upper edges of the platesv and F by placing a supporting-block J l' in the slot 1, as illustrated in Fig. 3. The adjustments above described having been eccomlished, the machine is ready for operation, this the o orator arranges the parts as illustrated in lookin the end plates F 1 2, to the frame H by the late es L and moving the medium of the lever H. hen this operation is complete, the molded bloek'is resting upon the pallet with its front face in contact with the plate I. To remove it, the pallet is slid outward between the guides la .and is lifted from the frame, after which the operation may be re eated.

As illustrated in i 2, the pallet J is of eater Width than t e block; but, as ha con described, it is immaterial whether it is of the same or of greater width.

To support the cores more rigidl in the mold, the pallet may be provided with In s m, which extend beneath the-inner end the core when the latter is in place within the mold, as illustrated in Fig. 2.
